background & importance: disc herniation is defined as the prolapsed of material disc into the spinal canal. if the disc fragment is free in spinal canal, it is called sequestration disc fragment. occasionally, alteration in sequestration disc fragment makes the diagnosis of the disc herniation, challenging. case presentation: we reviewed a rare case of the cervical sequestrated disc herniation...

Abstract Brucellosis is one of the most important zoonosis. It causes significant economic and medical problems in countries throughout the world, including Iran. According to the available literature, brucellosis rarely causes intracranial space-occupying lesions. In this case study, we reported an intracranial mass in a 52-year-old male who were affected with brucellosis. The patient was ref...

over half of all reported traumatic brain injuries are the result of a motor vehicle accident. other then the direct head impact itself, the sheer forces of the accident can cause the brain also to collide against the internal bone of the skull. in fact, when a moving head comes to a quick stop, the brain continues in its movement, striking the interior of the skull. this can cause bruising of ...

Primary thymic adenocarcinoma is a very rare malignancy of the anterior mediastinum with no standardized treatment. A 36-year-old male patient presented with hoarseness over the past 3 months. A chest computed tomography (CT) scan showed an infiltrative mass to the proximal vessels and aortic arch in left upper mediastinum (4.1×3.1×5.4 cm). Brain magnetic resonance imaging (MRI) showed focal le...

Primary intraosseous meningioma is a rare tumor, and atypical pathologic components both osteolytic lesion and dura and soft tissue invasion is extremely rare. A 65-year-old woman presented with a 5-month history of a soft mass on the right frontal area. MR imaging revealed a 4 cm sized, multilobulated, strongly-enhancing lesion on the right frontal bone, and CT showed a destructive skull lesio...

A 40-year-old male patient with progressive dementia presented adversive seizures, and CT scan showed an enlarging focal mass lesion in the right cerebral hemisphere. Cerebrospinal fluid examination and brain biopsy confirmed the diagnosis of neurosyphilis. After a course of penicillin therapy there was disappearance of the cerebral mass lesion and the CT scan showed focal atrophy in the right ...

Nonneoplastic demyelinating processes of the brain with mass effect on magnetic resonance imaging can cause diagnostic difficulties. It requires differential diagnosis between the tumefactive demyelinating lesion and the coexistence of neoplasm. We document the case of 41-year-old woman with clinical and radiological findings suggestive of multiple sclerosis. Additional investigations confirmed...

Background: A demyelinating lesion can present as a space occupying in Magnetic Resonance Imaging (MRI) brain. Lesions that have diameter greater than 2 cm is referred tumefactive lesion. These lesions mimic brain tumor, namely glioma or primary central nervous system lymphoma. Case presentation: We two female patients over 30 years old who presented with limb weakness. Their MRI demonstrated t...
